Its pretty darn easy, I used to have issues with my CO2 needle valve and went through CO2 like crazy with my alk all over the map. This is much easier.

You probably should have included Kalk in your poll...

I run a Ca reactor, but unlike most I have removed all the weaknesses in the system. Flow through the reactor is controlled by peristaltic pump and CO2 is controlled by pH probe and controller.

I also use Kalk in a Kalkreactor. It goes in only at night to help stabilize pH, but also contributes to Ca/Alk. Like my Ca Reactor, it is controlled by peristaltic pumps and monitored by pH.

Both Ca reactor and a passive kalk reactor.

My GEO Ca reactor was dead easy to set up and dial in. Maybe I was just lucky?

I manually dose reef designed products for calcium and alkalinity, and use littlesilvermax's magnesium.

I'll eventually be dosing exactly what Kien does but without any automation for a bit.

I dose Ca and Mg, and let water changes take care of alk (my IO mixes up pretty high).

Depends on which tank.
120gal Calcium Reactor and Kalkwasser Reactor
20gal Water changes only
135gal (not mine but I help to look after it) Kalkwasser and 2 part dosing by hand.

I use a calcium reactor and Littlesilvermax's magnesium. I used to use a kalk reactor but with the zeovit system it is not recommended. I test the alk once every few days (because it's really easy to test) to make sure my calcium reactor is maintaining my levels. Magnesium I test once a week during water changes to see if it needs "topping up".

I use both a Calcium reactor and Kalk. reactor. My yearly costs are considerably cheaper then what I budgeted out for a dosing system. I also run magnesium in my Calcium reactor, which generally gives me a 'set-it & forget it' option.
